							<li class="in">

								<p class="compact">API Updates</p>

								<ul class="nested compact flat">

									<li>
										<p>
											Init improvement: Don't fail if Flash URL is null in normal include + init case. Instead, show note in debug input and wait for <code>soundManager.setup()</code> with <code>url</code> param, then treat as delayed init case. Improved experience if including <code>&lt;script&gt;</code>, then trying to do <code>setup()</code> after DOM Ready (common jQuery case).
										</p>
									</li>

									<li>
										<p>
											<code>soundManager.setup({url:...})</code> + lazy-loading (dynamically-loaded JS) case: If <code>setup()</code> given url parameter after DOMContentLoaded has fired, assume we should start right away. (Helps reduce need for <code>beginDelayedInit()</code> + "just works" for most users)
										</p>
									</li>

									<li>
										<p>
											Don't init inline after <code>document.readyState === 'complete'</code> (improve lazy-loading case, wait for setup() with url: instead)

									</li>

								</ul>

							</li>

							<li class="in">

								<p class="compact">Bug fixes</p>

								<ul class="nested compact flat">

									<li>
										<p>
											Fix <code>'audio/mpeg'</code> <code>canPlay()</code> checks, was incorrectly returning false due to <code>audio/mpeg; codecs="mp3"</code> working and preventing <code>audio/mpeg</code> from being checked.
										</p>
									</li>

									<li>
										<p>
											More paranoid <code>Audio()</code> handling for "bad" Opera (&lt; 10) where <code>new Audio()</code> would throw not_enough_arguments (always required URL).
										</p>
									</li>

									<li>
										<p>
											Safer HTML5 duration checks - null now assigned instead of undefined.
										</p>
									</li>

									<li>
										<p>
											Improve durationEstimate under HTML5 during <code>whileloading()</code>.
										</p>
									</li>

									<li>
										<p>
											Flash 9/RTMP: Actually provide caption data to <code>oncaptiondata()</code>.
										</p>
									</li>

									<li>
										<p>
											Fix <code>SMSound.play({url:...})</code> "re-use" case where new URL wasn't being assigned + loaded right away, and <code>SMSound.url</code> property was not being updated.
										</p>
									</li>

									<li>
										<p>
											Correct <code>load()</code> and play() with new URL parameter, so that subsequent <code>play()</code> call uses new URL (and not URL assigned with original <code>createSound()</code> call).
										</p>
									</li>

									<li>
										<p>
											Use seconds for <code>SMSound.buffered</code> (time ranges) whether HTML5 or Flash, since SM2 API uses seconds for <code>setPosition()</code> etc.
										</p>
									</li>

									<li>
										<p>
											Correct <code>play()</code> -&gt; <code>pause()</code> -&gt; <code>setPosition(0)</code> -&gt; <code>play()</code> -&gt; <code>pause()</code> case where the latter wasn't firing due to invalid state.
										</p>
									</li>

								</ul>

							</li>

							<li class="in">

								<p class="compact">Miscellaneous</p>

								<ul class="nested compact flat">

									<li>
										<p>
											New Cassette Tape UI Prototype/demo (experimental).
										</p>
									</li>

									<li>
										<p>
											Tweaked documentation layout for legibility. Webfont (deja vu sans mono) from <a href="http://dejavu-fonts.org/" title="Deja Vu Fonts">dejavu-fonts.org</a> for code examples.
										</p>
									</li>

									<li>
										<p>
											Improved lazy-load / deferred example based on new <code>setup()</code> logic
										</p>
									</li>

									<li>
										<p>
											Added SMSound.buffered documentation
										</p>
									</li>

						<h3><b>V2.97a.20120624</b> - New <code>soundManager.setup()</code> method, numerous HTML5 improvements for <code>createSound()</code>, <code>load()</code>, progress and reuse cases, and minor flash audio bug fixes</h3>

						<ul>

							<li class="in">

								<p class="compact">API: New sugar-like stuff</p>

								<ul class="nested compact flat">

									<li>

										<p>
											 New <code>soundManager.setup()</code> mixin-style method for assigning properties and common start-up callbacks. Collects top-level soundManager configuration properties and object collections - <code>onready</code>, <code>ontimeout</code>, <code>defaultOptions</code>, <code>flash9Options</code> and <code>movieStarOptions</code> - under a single method call.
										</p>
										<p>
											<b>Upgrade / legacy note:</b> This is a modern replacement for the direct property assignment method used in all previous versions - eg., <code>soundManager.url = '/swfs/'</code> - the old method continues to work for legacy support, but you should migrate to using the new method as it's much cleaner. All included demos use the new method where applicable.
										</p>

										<p>
											<b>New <code>soundManager.setup()</code> method example</b>
										</p>

<pre class="block"><code>soundManager.setup({
  <span><span>// required</span></span>
  url: <span>'/path/to/swfs/'</span>,
  <span><span>// optional</span></span>
  flashVersion: <span>9</span>,

							<li class="in">

								<p class="compact">Bug fixes</p>

				 				<ul class="nested compact flat">

									<li>
										<p>
											Improve HTML5 audio load/playback reliability + stability on iOS, and for object reuse cases (<code>play()</code> -&gt; <code>load({url: ...})</code>. Prior behaviour was making initial HTTP request when object was created (meta/preload, not necessarily loading entire file.) Request now only happens with preload/load/play-related calls.
										</p>
									</li>

									<li>
										<p>
											HTML5: Firefox seems to have changed when unloading HTML5 audio, <code>url = ''</code> now loads hosting page HTML (boo) instead of <code>null</code> / no request. Changed to <code>about:blank</code> like everyone else. Also fixed boolean logic on <code>isMovieStar</code> assignment.
										</p>
									</li>

									<li>
										<p>
										    Add <code>audio/mp3</code> and related MIME checks for flash, correct edge case where <code>play({type:'audio/mp3'})</code> would use HTML5 when <code>preferFlash = true</code>, due to seeming lack of Flash support for the MIME type.
										</p>
									</li>

									<li>
										<p>
											Fixed old Flash 8 <code>onload()</code> edge case where loading from cache might return incorrect <code>didLoad: false</code> result - corrected by checking for a non-zero sound duration.
										</p>
									</li>

									<li>
										<p>
											Properly reset <code>SMSound.id3 = {}</code> with internal resetProperty and public methods like <code>load()</code>.
										</p>
									</li>

									<li>
										<p>
											Edge case fix: Don't attempt to remove flash unless reference exists (prevent false warning when <code>reboot()</code> called in 100% HTML5 mode.)
										</p>
									</li>

									<li>
										<p>
											Correct empty options JS error on internal <code>_setup_html5()</code> when reusing HTML5 audio object per <a href="https://getsatisfaction.com/schillmania/topics/possible_bug_when_html5_audio_tag_is_reused_20120527_release">V2.97a.20120527 bug report</a>
										</p>
									</li>

									<li>
										<p>
											Fix minor false positive (undocumented error handler case) with HTML5 <code>play()</code> falsely reporting 32-sound ceiling edge case and calling <code>SMSound.onplayerror()</code> (if assigned) when using flashVersion = 9. Should only apply when flash 9 is being used for playback, and ceiling hit.
										</p>
									</li>

								</ul>

							</li>

							<li class="in">

								<p class="compact">Miscellaneous</p>

				 				<ul class="nested compact flat">

									<li>
										<p>
											Finally assign + use <code>SMSound.id</code> (instead of sID), matching <code>createSound({id: 'foo'})</code> pattern; maintain legacy sID property (ancient behaviour, originally intended to avoid potential namespace conflicts many years ago - now silly and not a concern.)
										</p>
									</li>

									<li>
										<p>
											Improved handling of <code>whileloading()</code> vs. HTML5 <code>onload</code> (when using HTTP range/partial requests).
										</p>
										<p>
												HTML5 <code>onload()</code> (now triggered via native <code>canplaythrough</code> event) may fire early, followed by numerous HTML5 <code>progress</code> requests during playback as the audio object requests and buffers more audio ranges (eg., 0-10 seconds), eventually matching the total sound duration.
										</p>
										<p>
												Bytes loaded / total are not available, so bytesLoaded instead reflects a fraction of "duration loaded", between 0 and 1 as data is buffered in. Previously, <code>whileloading</code> events would not fire once <code>onload</code> had fired under HTML5.
										</p>
									</li>

									<li>
										<p>
											New (undocumented, for now) <code>buffered</code> array on SMSound objects; list of objects following the pattern <code>SMSound.buffered = [{ start: 0, end: 706 }]</code> representing loaded time ranges (somewhat similar to HTML5 TimeRanges spec, but using static properties instead of method calls with an index parameter.) Array will initially be empty, zero-length. This can be looped through to show overlays of "loaded" time fragments on progress bars, for example.</p>
										<p>SMSound <code>buffered</code> is updated during <code>whileloading()</code> calls, where values are provided by the browser. For flash, will always be one item with <code>{ start: 0, end: SMSound.duration }</code> assigned. Also stopped sending 1/1 values to <code>whileplaying()</code> at <code>onload()</code>, since HTML5 can fire <code>onload()</code> (via <code>canplaythrough</code>) very early followed by many progress (<code>whileloading()</code>) events.
										</p>
										<p>
											<b>Support note:</b> Not all browsers (eg., Safari 5.1.7) appear to provide buffer / TimeRanges data for HTML5 audio objects. At time of writing (06/2012), Firefox, Chrome Canary, IE 9 and Opera provide TimeRanges alongside progress events.
										</p>
									</li>

									<li>
										<p>
											Upgraded demos to use to <code>soundManager.setup({...})</code> for most configuration cases (vs. setting <code>soundManager.url</code>, <code>soundManager.defaultOptions.autoLoad</code> directly etc.)
										</p>
									</li>

									<li>
										<p>
											Warn if <code>soundManager.setup()</code> called with <code>url</code> or <code>flashVersion</code>, and init has already fired (ie., flash options already set + movie already loaded) where changes will not take effect until <code>soundManager.reboot()</code>.
										</p>

									</li>

									<li>
										<p>
											Assign top-level soundManager properties (eg. <code>soundManager.url</code>) from <code>soundManager.setupOptions</code> at <code>DOMReady</code> time; this allows legacy <code>soundManager.url = ...</code> assignment to work, and helps to ensure legacy-style, directly-assigned top-level property values get written back to <code>soundManager.setupOptions</code>.

						<h3><b>V2.97a.20120527</b> - Fix for <code>ontimeout()</code> regression. GWT/JSNI compatibility, slow connection and Safari "background tab" SWF load handling improvements (<a href="../../download/soundmanagerv297a-20120527.zip" class="norewrite">Download archived version</a>)</h3>

						<ul>

							<li class="in">

								<p class="compact">Bug fixes</p>

				 				<ul class="nested compact flat">

									<li>
										<p>
											Fix for <code>ontimeout()</code> regression seen when using lazy-loading / SM2_DEFER introduced with V2.97a.20120513; bug introduced when making edits to pass newer jslint rules regarding <code>return</code> within <code>if...else</code> blocks.
										</p>
									</li>

									<li>
										<p>
											Replaced <code>instanceof Function</code> with "safer" <code>typeof x === 'function'</code> for <code>onready()</code>, <code>ontimeout()</code> and related callback argument checks as GWT + JSNI was passing arguments that failed the <code>instanceof</code> check. (Related <a href="https://getsatisfaction.com/schillmania/topics/gwt_jsni_problems_with_onready_and_ontimeout-ucvp8">bug report</a>.)
										</p>
									</li>

									<li>
										<p>
											Corrected another small regression for the <code>ontimeout()</code> -&gt; <code>onready()</code> "recovery" edge case, ensuring "ready" does not fire after a timeout when init was unsuccessful.
										</p>
									</li>

								</ul>

							</li>

							<li class="in">

								<p class="compact">Miscellaneous</p>

				 				<ul class="nested compact flat">


									<li>
										<p>
											Improved handling for special Safari page load case: When a new tab is opened that does not have focus, the Flash SWF does not load/init until the tab is brought to the foreground. SM2 now recognizes this special case and waits until <code>window.onfocus()</code> before attempting to do the JS/Flash part of init. Previously, it would fail with a timeout.
										</p>
										<p>
											Code written to originally handle Safari 3.1, which did not support <code>document.hasFocus()</code>, was modified and updated for this purpose. The Safari 3.1 logic previously deferred SM2's start-up in a similar fashion. (The old Safari 3.1 <code>mousemove()</code> focus-detection hack has been removed as Safari 4 has been out since mid-2009, and Safari 5 since mid-2010.)
										</p>

									</li>

									<li>
										<p>
											SM2 init process will now delay and retry if no Flash response, and SWF has loaded &gt; 0 and &lt; 100%. Timeout will now happen only after delay and when SWF has loaded 100%. Should help prevent first-visit (non-cached) failure on very slow or laggy connections.
										</p>

									</li>

									<li>
										<p>
											Added note about potential Firefox regression: Offline JS/Flash start-up (viewing HTML pages via <code>file://</code> and/or <code>c:/</code> and so forth), possibly not working as of Firefox 9 and newer (at time of writing, also up to and including Firefox 12), even despite special security whitelisting under Flash Player "trusted locations" preferences / control panel.
										</p>
										<p>
											After successful Flash -&gt; JS call, SM2's "return" JS -&gt; Flash call fails with unusual JS/Flash exception, "Error in ActionScript" error with no further detail. Offline viewing still works in other browsers.

											Fix <code>play()</code> "<code>from</code>" + "<code>to</code>" sound sprite playback issue: In some cases, previously-fired "to" events were re-firing due to not being removed, because an equality check was comparing against a potential "to" value of a string rather than a number.

										<p>
											HTML5: Fixed <code>Audio()</code> <code>src</code> attribute re-assignment bug seen in <code>createSound()</code>-&gt;<code>play()</code> use case.
										</p>
									</li>

									<li>
										<p>
											HTML5: <code>mySound.load({onload:function(){}})</code> callback fixed so it works.
										</p>
									</li>

									<li>
										<p>
											HTML5 + Flash: <code>onload()</code> now called immediately when <code>load({onload:function(){}})</code> is used on a sound with the same URL which has already loaded.
										</p>
									</li>
		
									<li>
										<p>
											<code>onstop()</code> now mimics <code>onfinish()</code> in terms of sequence. HTML5 sets <code>position</code> to 0, but retains pre-<code>stop()</code> position property value (like Flash does.)
										</p>
									</li>

									<li>
										<p>
											Amazon Kindle Fire UA looks like Safari on OS X 10.6.3, but does not have broken HTML5 audio (i.e., intermittent playback failure) like the "isBadSafari" case.
										</p>
									</li>

									<li>
										<p>
											MovieStar/NetStream (non-RTMP) edge case: Correct <code>onfinish()</code> after <code>play()</code> and a seek so that it always fires. Remove <code>metadata()</code> after first call (as it was) for non-RTMP. Reduce buffer-near-end logic to 3 seconds from 5.
										</p>
									</li>

									<li>
										<p>
											Flash 9 MovieStar/RTMP: Only fire <code>onconnect()</code> for RTMP (was firing for flash 9/NetStream, too, breaking MovieStar <code>createSound({autoLoad:true,onload:function(){this.play()}})</code> case.)
										</p>
									</li>

									<li>
										<p>
											RTMP: Exclude RTMP from 30-second <code>resume()</code> reposition hack (streaming does not have this issue.) May have been breaking buffer due to seek on resume.
										</p>
									</li>

									<li>
										<p>
											Fix edge case where <code>soundManager.waitForWindowLoad = true</code> (non-async startup case), but <code>_initComplete()</code> may fire after <code>window.onload()</code> and thus <code>onready()</code> never fired.

							</li>

							<li class="in">

								<p class="compact">API updates</p>

				 				<ul class="nested compact flat">

									<li>
										<p>
											Added <code>soundManager.html5PollingInterval</code> property, for increased <code>whileplaying()</code> callback frequency (higher UI framerates) similar to <code>flashPollingInterval</code>. (By default, null/off.) Also excludes mobile (eg., iOS) by default.
										</p>
									</li>

									<li>
										<p>
											<code>soundManager.onPosition()</code>: Queues a callback that will be fired each time a sound reaches a given position during playback. Applies for the life of the sound object.
										</p>
									</li>

									<li>
										<p>
											<code>soundManager.clearOnPosition()</code>: Removes <code>onPosition()</code> callback(s) from a sound, by position and/or callback. (If no position or callback are specified, then all callbacks are cleared for the given sound.)
										</p>
										<p>
											Optionally, an <code>onstop: function(){}</code> handler can be passed to capture the moment when "to" is reached. When using Flash, sound is preloaded 100% in order to guarantee playback can start at the "from" position.
										</p>
									</li>

									<li>
										<p>
											Added support for "audio sprites." New sound options, <code>from</code> and <code>to</code> allow segments, samples or slices of sound to be played. eg., <code>mySound.play({ from: 5000, to: 10000});</code>
										</p>
									</li>

									<li>
										<p>
											New sound option, <code>onposition</code>, defines times and related callbacks for positions of interest within a sound. Applies on a per-play basis. eg. <code>onposition: {500: function(p) { console.log('position ' + p + ' was reached.') } }</code>
										</p>
									</li>

									<li>
										<p>
											Experimental: Multiple formats/encodings support in the sound <code>url</code> parameter; now accepts an array as an alternate to a single string. eg. <code>soundManager.createSound({id:'foo', url:['bar.ogg','bar.mp3']});</code> - SM2 will use the first playable URL it finds and the URL property will then reflect the one URL after that point. Note that this means the original array data will be lost.
										</p>
										<p>
											Also accepts <code>type</code> attributes, eg. <code>url:[{type:'audio/mp3',url:'/path/to/play.php?song=123'},...]</code> - useful for URLs without obvious filetype extensions.
										</p>
									</li>

									<li>
										<p>
											Flash 9 + MovieStar (NetStream) / RTMP: <code>onmetadata</code> (sound parameter) callback, allows capturing of metadata events from flash (eg., streaming song / title updates) similar to <code>onid3()</code>. Can now fire multiple times, eg., when RTMP streaming and new song / artist info is provided.
										</p>
									</li>

									<li>
										<p>
											Added JS version + Flash SWF build/version check to SM2 during start-up. (Finally! :D) ... Will now throw <code>new Error()</code> if soundmanager.js version reports V2.97a.20111030 and SWF version is V2.97a.20110918, for example. (Happens when upgrading/replacing old versions of SM2, you may forget to update one of the SWFs etc.)

Combined demo JS + CSS files for performance; cut HTTP requests by over 50% (now down to 14 HTTP requests in most cases) via concatenation and data: URIs for some background images and sprites.
										</p>
									</li>

									<li>
										<p>
											360 player demos: Updated UI with more circles and a few gradients, border-radius etc. Small 50x50 UI is now clickable over entire area, rather than small circular button.
										</p>
									</li>

									<li>
										<p>
											Demos: Some data: URIs added to inline player and 360 player for performance (reduced HTTP requests.) Christmas lights demo now uses YUI 3 seed + animation.
										</p>
									</li>

									<li>
										<p>
											<code>soundManager.useConsoleOnly = true</code> by default, was previously false. New "true" default means no HTML debug output if <code>console.log()</code> is available.
										</p>
									</li>

									<li>
										<p>
											soundmanager2.js: Micro-optimizations, further -nodebug-jsmin optimizations and minor comment formatting. Eliminated last Google Closure Compiler warning (caused by an empty "if" block.)
										</p>
									</li>

									<li>
										<p>
											Debug output no longer shows "loops: 1" (redundant), only interesting values eg. 2+ are reported.
										</p>
									</li>

									<li>
										<p>
											Documentation: Small theme tweaks, textured background and re-organization of properties (left menu) for easier navigation. Fixed "onsuspend" event labeling, clarify SMSound events as properties and not methods. Re-sorted property lists, tidied up code formatting. Added missing <code>soundManager.onPosition()</code> documentation (side note: previously named onposition(), old lower-case method name maintained for backward compatibility.)

										<p>Clean-up time! The following soundManager properties have been removed as they're ineffective and/or have modern replacements:</p>

										<p>
											<code>soundManager.nullURL = 'about:blank';</code> (internalized; search for 'about:blank' in the source if you want to customize it.)
										</p>

										<p>
											<code>soundManager.allowPolling = true;</code> (ignored, always true now. <code>whileloading()</code> / <code>whileplaying()</code> calls rely on it.)
										</p>

										<p>
											<code>soundManager.useFastPolling = false;</code> (redundant, now determined by flashPollingInterval now being specified as a number eg., 20, instead of the default of null.)
										</p>

										<p>
											The following SMSound (sound options) have been removed, in favour of modern replacements (and also didn't work with HTML5 sounds.)
										</p>

										<pre class="block"><code>soundManager.defaultOptions.onbeforefinish = null;
soundManager.defaultOptions.onbeforefinishtime = 5000;
soundManager.defaultOptions.onbeforefinishcomplete = null;
soundManager.defaultOptions.onjustbeforefinish = null;
soundManager.defaultOptions.onjustbeforefinishtime: 200;</code></pre>

										<p>
											As a replacement, use the <code>SMSound.onposition()</code> method to assign an event callback handler to fire at the relevant time.
										</p>

<pre class="block"><code>mySound.onposition(10000, function() {
  console.log('the sound ' + this.id + ' is now at position ' + this.position);
});</code></pre>

										<p>
											If you need to fire an event relative to the true end of the sound, reference its duration once the sound has fully-loaded - ie., at or after the <code>onload()</code> event - as the duration will not be completely accurate until that time. <code>durationEstimate</code> may be referenced before <code>onload()</code>, but it should not be relied on when "precise" timings of say, &lt; 1 second are desired.
										</p>

<pre class="block"><code>mySound.load({
  onload: function() {
    this.onposition(this.duration - 5000, function() {
      console.log('the sound ' + this.id + ' is now at position ' + this.position);
    }
  }
});</code></pre>

										<p>
											Again, note that due to the interval / polling-based methods of both HTML5 and flash audio, sound status updates and thus precision can vary between 20 msec to perhaps 0.5 seconds and the sound's position property will reflect this delta when the onposition() callback fires.
										</p>

									</li>

									<li>

										<p>Added <code>soundManager.onposition()</code> (forgot to mirror the SMSound method)</p>

									</li>

									<li>

										<p>
											Privatize <code>soundManager.netStreamMimeTypes</code>, etc. <code>soundManager.mimePattern</code>, the resulting one applied to <code>canPlayMIME()</code> etc., is still exposed.
										</p>

									</li>

									<li>

										<p>
											Simplify getMovie() to use _id(smID) || _doc[smID] || _win[smID] rather than IE / Safari special checks. Sometimes (old?) IE and Safari would return null on getElementById(), but window[id] or document[id] would work. Presumably related to Flash + ExternalInterface wackiness.

									<li>A regression was introduced in V2.97.20110706 where SM2 would fail to start in HTML5-only mode on supported desktop browsers when flash was disabled or not installed, eg., Safari on new Macs or IE 9 without flash. (iOS was not affected.) This has been fixed with the 2.97.20110801 release.</li>

									<li>
									 <p><code>soundManager.useHTML5Audio</code> is now <code>true</code> by default; however, <code>soundManager.preferFlash</code> is also <code>true</code> and HTML5 browsers will still attempt to use flash for playing MP3/MP4 by default, if those formats are marked as "required".</p>
									 <p>If you wish to have 100% HTML5 mode in more cases, set <code>soundManager.preferFlash = false</code>. Presently, the MP3 links and MP3 button SM2 demos are more HTML5-friendly and will serve as a test for exposing bugs that may be in the wild.</p>
									</li>

									<li>
									 <p><code>soundManager.html5Test</code> has been relaxed to use <code>(probably|maybe)</code> for Audio's <code>canPlayType()</code> test (previously, was only "probably") - so formats will be more likely to work on HTML5-only devices that conservatively report "maybe" for MIME types like <code>audio/mpeg; codecs="mp3"</code> at this point.</p>
									</li>

									<li>
									 <p>Certain mobile and tablet-like devices are special-cased as preferring HTML5, and will ignore checking for flash altogether; this presently includes the iPad, iPhone and iPod, Palm Pre and Motorola Xoom.</p>
									</li>

									<li>
									 <p>The HTML5 audio "loadeddata" event triggers an SMSound <code>onload()</code> event, which now fires <code>whileplaying()</code> and tries to pass identical <code>bytesLoaded, bytesTotal</code> parameters so that UIs will correctly show the sound as fully-"loaded" - even if in truth, not all bytes have actually been fetched (depending on the browser and server, etc.) because of the ability to do arbitrary seeking.</p>
									</li>

									<li>
									 <p>Updated Flash 9 <code>onfinish()</code> / end-of-sound behaviour: Sound objects' <code>position</code> property no longer resets to 0 when a sound ends (and when <code>onfinish()</code> fires.) This now matches both HTML5 and flash 8's existing behaviour; therefore, a sound's <code>position</code> will equal its <code>duration</code> at <code>onfinish()</code> in all cases now. In the event <code>play()</code> is called from the end of a sound at or after <code>onfinish()</code>, the sound's position will be set to 0 before playback begins if using flash 9.</p>
									<p>Edge case covered: if at internal SOUND_COMPLETE the SMSound.position is &lt; its duration, flash will match position to duration and fire <code>whileplaying()</code> one last time so "100%" is always reached before <code>onfinish()</code> is called.</p>
									<p><code>multiShot</code> + <code>multiShotEvent</code> case has been verified as working (eg. <code>onfinish()</code> fires 5x if <code>play()</code> called 5x.)</p>

						<p class="note">Special note: This <i>was</i> <b>V2.97a.20110705</b>, but the latest Flex SDK (4.5.1.21328) was downloaded and used for this build, and it compiled a Flash 9 SWF that wouldn't fully-start on <i>some</i> Windows machines running Firefox and IE 7, possibly others - thus, SM2 would fail to start up. The Flash 9 SWFs are now compiled with an older, working SDK version 4.1.0.16076, used in previous working releases. See <a href="http://getsatisfaction.com/schillmania/topics/flashversion_9_fails_to_initialize_but_only_on_windows">discussion</a> for more details.</p>

						<p>Improved "mixed mode" HTML5/flash handling via new (experimental) <code>preferFlash</code> option, enabled by default. (If present, MP3/MP4 get flash for stability; HTML5 is used for other formats.) OS X 10.6.8 (finally?) fixes HTML5 audio in Safari. SoundManager 2 SWF adjusted to fall under ClickToFlash's "invisible" rules, may lower chance of blocking.</p>

						<ul>

							<li class="in">

								<p class="compact">Bug fixes</p>

				 				<ul class="nested compact flat">

									<li>ClickToFlash (Safari/Mac flashblock-style extension) compatibility improvement: Use <code>width/height: auto</code> on SWF instead of 100%. The latter is not recognized as being within ClickToFlash's &lt;= 8x8px "invisible flash" rules, almost guaranteed to be blocked. (When considered "invisible", SWF is allowed to load normally if user has the invisibles option enabled.)</li>

									<li>Flash blocking/handling improvements: Default <code>#sm2-container</code> size now always 8x8px to fall under "invisible" flash rules, better chance of load being allowed. If blocked and using flashblock.css, <code>#sm2-container</code> reverts to 48x48px at <code>ontimeout()</code> for visibility (so user can see, and unblock the flash bit.)</li>

									<li>OS X 10.6.8 "pre-Lion release" update <i>finally</i> appears to have fixed the broken Safari HTML5 audio issue. Thus, audio was broken from OS X 10.6.3 to 10.6.7 and SM2 will use Flash for these known cases. Related: <a href="http://isflashdeadyet.com/tests/safari-html5/">Testcase</a> and Webkit bug <a href="https://bugs.webkit.org/show_bug.cgi?id=32159">#32159</a>.</li>

									<li>HTML5 audio: Playback now does not start after a <code>setPosition()</code> call (if the sound was not already playing), or if it was paused - matching the existing Flash API behaviour.</li>

									<li>Fix <code>ontimeout()</code> queue incorrectly processing after <code>onload()</code> and successful startup.</li>

									<li>Debug output: extraneous "%s" fixes for <code>onready()</code> / <code>ontimeout()</code></li>

							</li>

							<li class="in">

								<p class="compact">API Updates</p>

								<ul class="nested compact flat">

									<li>
										<p>Added experimental <code>soundManager.preferFlash</code> (default:<code>true</code>) for a more consistent MP3/MP4 playback option in certain HTML5 cases. If using <code>soundManager.useHTML5Audio</code> + <code>preferFlash</code> and flash is available, flash will be used for MP3/MP4.</p>
										<p> HTML5 is still new and relatively unstable, and bugs are yet to be found and fixed across a growing number of browsers/platforms etc. (consider that it was broken on Safari between OS X 10.6.3 and 10.6.7.) If flash is not installed or <code>preferFlash = false</code>, 100% HTML5 mode can still apply. In any event, HTML5 will still be used (if enabled) for all other formats.</p>
									</li>

									<li>Moved internal html5Only to (experimental) <code>soundManager.html5Only</code>, for detecting "HTML5-only mode" - eg., iOS, Safari without <code>preferFlash</code> or other environments where SM2 is operating without the flash portion of SM2.</li>

									<li>360&deg;, inline, MP3 button players: Event add/remove: use addEventListener based on typeof attachEvent === null (old IE behaviour)</li>

									<li>MP3 player button demo: Fix IE 6/7 display issue on button (d'oh!)</li>

									<li>Muxtape-style demo: Added <code>pagePlayer.playPrevious()</code>, to match <code>pagePlayer.playNext()</code> (call when a sound is currently playing.)</li>

									<li>Fixed 360&deg; player basic visualization demo (missing class in HTML), clarified canvas support (no eq/spectrum) re: IE &lt;9.</li>

									<li>360&deg; UI: Old "empty element doesn't catch mouse events" bug apparently still applies to IE 9. Fix with invisible background image.</li>

				   <li>New <code>soundManager.onready(myFunction[,scope])</code> method, for asynchronous queueing of <code>onload()</code>-style handlers. Fires when SM2 has finished initialising. Accepts an <i>optional</i> scope parameter to apply to handler; if none given, window object is used. A "status" object is passed to your handler (can be ignored) which includes a <code>success</code> boolean indicating whether SM2 loaded OK or not. Handlers added via onready() after successful initialisation will fire immediately.</li>
				   <li>New <code>soundManager.oninitmovie()</code> event callback, single assignment similar to <code>onload()</code>. Fires when the flash movie has first been written to (or read from) the DOM. Used internally for a flashblock-handler-related example, custom timeout condition.</li>
				   <li>New <code>soundManager.useFastPolling</code> property (false by default), enables 1 msec Flash 9+ timer for highest-possible <code>whileplaying()</code> and related JS callback frequency (default is 20 msec.) Use with <code>soundManager.useHighPerformance = true</code> for best performance, frame rates while updating the UI via whileplaying() etc.</li>
				   <li>New sound option (soundManager.defaultOptions): <code>multiShotEvents</code> (default:false) - enable support for multiShot-style events (currently <code>onfinish()</code> only). Eg. When <code>mySound.play()</code> is called three times, <code>onfinish()</code> will subsequently fire three times.</li>

				   <li><code>createSound</code> now writes a warning to debug output if the sound ID is a number, or is a string starting with a numeric character. Because SMSound objects are stored in <code>soundManager.sounds[]</code>, while not syntactically invalid, numeric IDs will be treated as array indices and are likely to break things.</li>

				  <ul class="nested compact flat">

				   <li>New <code>SMSound.ondataerror()</code> (flash 9+) handler for cases where waveform/eq data is inaccessible due to other flash movies in the current browser which have loaded sound. (Flash must have security permissions to "read" all data currently being output, long story short. Having a YouTube tab open can cause this, for example.)</li>

SM2 will now revert wmode to default for this case (losing transparency/layering of movie) - <i>or</i> set <code>soundManager.flashLoadTimeout</code> to 0 and SM2 will retain wmode, but must now wait potentially infinitely for flash to load (until user scrolls it into view.) <code>soundManager.specialWmodeCase</code> reflects if this fix has been applied after init time. </li>

Strange bug with JS/flash communication breaking with wmode=opaque on flash, specific (?) to Firefox on windows. SM2 does not normally set wmode.

			       <li class="in">Fixed some memory "leaks" / garbage collection issues. RAM allocated to load sounds previously wasn't freed until page unload; now memory should be garbage collected some time after <code>sound.unload()</code> and/or <code>soundManager.destroySound()</code>/<code>sound.destruct()</code> methods are called. In certain cases, Flash sound objects may be destroyed and re-created (transparent to the JS-side) to release memory. Note that garbage collection is not instantaneous, and is affected by CPU/system load and other variables.</li>
			       <li class="in">Fixed an issue with <code>play()</code> not working on sounds created with <code>autoPlay</code>.</li>

			    <h3>V2.5b.20080501</h3>
			    <p class="compact"><b>Warning:</b> A little experimental too, read details below.</p>
			    <p><em>Changelog</em>:</p>
			    <ul class="nested">
				 <li class="in">Rewrote SoundManager initialisation: "Way faster." Communication now initiated from Flash, verification callback then performed by JS; far faster, hopefully more-reliable (TBD.) Init time drastically reduced from seconds to milliseconds in most cases, dependent primarily on Flash movie load rather than <code>window.onload()</code>.</li>
				 <li>Above change also fixes Safari "loading SM2 in background tab" issue, where Safari does not init Flash until background tab comes into focus (when a link is opened in a new, non-focused tab.)</li>
				 <li class="in">Current drawback: Difficult to determine, save for falling back to <code>window.onload()</code> plus focus methods due to above issue, whether SM2 is actually available or not (ie., <code>soundManager.onerror()</code> will not likely be called as in past.) However, the <code>supported()</code> method will correctly reflect if SM2 has successfully initialised, for example.</li>
				 <li class="in">Added sandbox/security model code; SM2 can now tell if it is restricted to either local or internet access only, for example. Helpful in potential debugging errors, plus viewing demos off the local filesystem should no longer throw init errors requiring whitelisting (seemingly due to the new initialisation method.) Win!</li>
				 <li class="in">Opera 9.27 has been noted to have some bugs relating to ExternalInterface, seems to be unable to make calls from ActionScript-level methods using <code>setTimeout()</code> or <code>setInterval()</code>. As a reulst, SoundManager 2 events like <code>onfinish()</code>, <code>whileplaying()</code> and <code>onfinish()</code> can be sporadically called or missed altogether. No known workaround at this time, but Opera 9.5 (beta 2) does not have this issue. Popular MP3 "mix tape" site muxtape.com uses similar techniques for JS-Flash communication and appears to suffer from the same problem.</li>
				 <li class="in"><strong>Warning</strong>: Random crash issue noticed when using IE 6 + 7 and this demo page, calling <code>createSound()</code> when <code>soundManager.defaultOptions.autoLoad = true;</code> from within <code>soundManager.onload()</code>, for creating + preloading the tab/theme switch sounds. Removing autoLoad=true (leaving the default of false) fixed the crash. Exact reason not determined, perhaps recursive calls or pre-onload issue (?), seems to be isolated to the home page. MPC demo uses autoLoad also, but did not crash. Mentioning just in case.</li>
			         <li>Updated Muxtape-style demo: More themes, load/security debugging info etc.</li>
			    </ul>
			   </li>

			 <h5>HTML5 Audio: Support updates, technical notes, quirks, bugs and annoyances</h5>

			 <p class="note">Note: This section is archived content and has been rolled into <a href="#revision-history">Revision History</a>.</p>

			 <p><b>As of the V2.97.20111220 release of SM2:</b></p>

             <ul>

			  <li>
				<p>Multiple URLs (and/or multiple MIME types) can be specified when creating a sound, thus allowing for better native HTML5 support between OGG, MP3 and others. See <a href="#smsound-url">SMSound.url</a> for details.</p>
			  </li>

			  <li>
				<p>Support for "audio sprites" has been added in the form of <code>from</code> and <code>to</code> sound options. See the <a href="../demo/api/#fitter-happier" title="SoundManager 2 audio sprite demo">audio sprite demo</a> for a live example.</p>
			  </li>

              <li>
				<p>Added <code>soundManager.html5PollingInterval</code>, for increased <code>whileplaying()</code> callback frequency (higher framerates.) Excludes mobile (eg., iOS) by default.</p>
			  </li>

              <li>
				<p>Fixed <code>Audio()</code> object <code>src</code> property re-assignment bug seen in <code>createSound()</code>-&gt;<code>play()</code>.</p>
			  </li>

              <li>
				<p><code>mySound.load({onload:function(){}})</code> callback fixed so it works.</p>
			  </li>

              <li>
				<p><code>onload()</code> now called immediately when <code>load({onload:function(){}})</code> is used on a sound with the same URL which has already loaded.</p>
			  </li>

              <li>
				<p><code>onstop()</code> now mimics <code>onfinish()</code> in terms of sequence. HTML5 sets position to 0, but retains pre-<code>stop()</code> position property value (like Flash does.)</p>
			  </li>

              <li>
				<p>Amazon Kindle Fire UA looks like Safari on OS X 10.6.3, but does not have broken HTML5 audio (i.e., intermittent playback failure) like the "isBadSafari" case.</p>
			  </li>

              <li>
				<p>Side note: iOS ignores volume, always returns value of "1" (at least, on iOS 4 and present iOS 5 releases.) See <a href="http://developer.apple.com/library/safari/documentation/AudioVideo/Conceptual/HTML-canvas-guide/AddingSoundtoCanvasAnimations/AddingSoundtoCanvasAnimations.html">related notes</a>.</p>
			  </li>

		     </ul>

			 <p><b>As of the V2.97.20111030 release of SM2:</b></p>

             <ul>

              <li>
				<p>Fixes for HTML5 <code>unload()</code> on Webkit (connection was not closing) due to src being set to <code>''</code> (OK only in Firefox, presently?) vs. an "empty" URL.</p>
			  </li>

              <li>
				<p>HTML5 <code>suspend</code> events are now listened for and fired via SMSound option <code>onsuspend()</code>. This event may be the best way to detect when mobile Safari (eg. iOS) is blocking autoplay-style behaviour, and user interaction is required to start or resume playback. (iOS does not allow auto-play of audio; user interaction is required for audio playback to start.)</p>
			  </li>

              <li>
				<p>Added try...catch for dumb IE 9 <code>Audio()</code> "not implemented" error in Windows server case without "desktop experience" installed, means no HTML5 audio/video support. Hat tip: Modernizr issue 224.</p>
			  </li>

			 </ul>

			 <p><b>As of the V2.97.20110801 release of SM2:</b></p>

             <ul>
              <li><p>A regression was introduced in V2.97.20110706 where SM2 would fail to start in HTML5-only mode on supported desktop browsers when flash was disabled or not installed, eg., Safari on new Macs or IE 9 without flash. (iOS was not affected.) This has been fixed with the 2.97.20110801 release.</p></li>
              <li>
               <p><code>soundManager.useHTML5Audio</code> is now <code>true</code> by default; however, <code>soundManager.preferFlash</code> is also <code>true</code> and HTML5 browsers will still attempt to use flash for playing MP3/MP4 by default, if those formats are marked as "required".</p>
               <p>If you wish to have 100% HTML5 mode in more cases, set <code>soundManager.preferFlash = false</code>. Presently, the MP3 links and MP3 button SM2 demos are more HTML5-friendly and will serve as a test for exposing bugs that may be in the wild.</p>
              </li>
              <li>
               <p><code>soundManager.html5Test</code> has been relaxed to use <code>(probably|maybe)</code> for Audio's <code>canPlayType()</code> test (previously, was only "probably") - so formats will be more likely to work on HTML5-only devices that conservatively report "maybe" for MIME types like <code>audio/mpeg; codecs="mp3"</code> at this point.</p>
	          </li>
              <li>
               <p>Certain mobile and tablet-like devices are special-cased as preferring HTML5, and will ignore checking for flash altogether; this presently includes the iPad, iPhone and iPod, Palm Pre and Motorola Xoom.</p>
              </li>
              <li>
               <p>The HTML5 audio "loadeddata" event triggers an SMSound <code>onload()</code> event, which now fires <code>whileplaying()</code> and tries to pass identical <code>bytesLoaded, bytesTotal</code> parameters so that UIs will correctly show the sound as fully-"loaded" - even if in truth, not all bytes have actually been fetched (depending on the browser and server, etc.) because of the ability to do arbitrary seeking.</p>
              </li>
              <li>
				<p>The experimental <code>soundManager.useGlobalHTML5Audio</code> and <code>soundManager.requireFlash</code> properties were removed. Internally the global HTML5 audio logic still applies to iOS, but it does not seem to be necessary for other devices at this time.</p>
			  </li>
             </ul>

			 <p><b>As of the V2.97.20110706 release of SM2:</b></p>

             <ul>
              <li><p>HTML5 audio appears to have been <i>fixed</i> in Safari with Snow Leopard 10.6.8, the "pre-Lion release", from 06/2011. SM2 will now only blacklist Safari + OS X 10.6.3 through 10.6.7 as having broken HTML5 audio (intermittent load/playback failures), and falling back to Flash where available.</p></li>
              <li>
               <p>New, experimental <code>soundManager.preferFlash</code> for handling "mixed-mode" HTML5 + flash cases. In the event HTML5 supports MP3/MP4 and <code>preferFlash</code> is true (and flash is installed), flash will be used for MP3/MP4 content while allowing HTML5 to play OGG, WAV and other formats etc.</p>
               <p><em>Important note:</em> Because HTML5 audio is still quirky and has bugs, <code>preferFlash</code> is <code>true</code> by default to help ensure MP3/MP4 play consistently. If set to <code>false</code> or flash is not available, "HTML5-only" mode will kick in and will apply to all formats.</p>
              </li>
             </ul>

			 <p><b>As of the V2.97.20110424 release of SM2:</b></p>

             <ul>
              <li><p>HTML5 audio in Safari on Snow Leopard 10.6.3 through 10.6.9 (10.6.7 was released 03/2011) are blacklisted and will fall back to Flash. 10.6.8 and 10.6.9 are preemptive guesses. According to beta testers, OS X 10.7 ("Lion") has fixed the intermittent <a href="https://bugs.webkit.org/show_bug.cgi?id=32159">HTML5 audio load/playback issue</a>.</p></li>
              <li><p><code>new Audio(null)</code> is no longer used for iOS, as iOS would attempt to load a URL called "null".</p></li>
              <li><p>iOS 4.2 or 4.3 may have introduced new security restrictions around <code>onfinish()</code>-&gt;<code>unload()</code>-&gt;<code>play()</code> that prevents the "play-through" behaviour previously allowed in certain cases. The <code>unload()</code> attempts to nullify the audio's <code>src</code> attribute, breaking the future <code>play()</code> request. The Muxtape/button/link demos were affected by this, and have been fixed with this release. To prevent this issue in your own apps, avoid <code>unload()</code> and simply use <code>onfinish()</code>-&gt;<code>play()</code> for iOS.</p></li>
             </ul>

			 <p><b>As of the V2.97.20110306 release of SM2:</b></p>

			 <ul>
              <li><p>Testing suggests that auto-play ("auto-annoy?") does work on iOS 4.1, but are aggressively blocked as of iOS 4.2.</p></li>
              <li><p><code>_resetProperties()</code> when setting Audio().src, fix sound1.play() -&gt; sound2.play() -&gt; sound1.play() case on iOS 4.1 not correctly re-assigning original sound URL (related to global audio object.)</p></li>
              <li><p>If no flash is detected, try forcing <code>useHTML5Audio = true</code> (eg. desktop safari on new Macs which don't come with Flash.) Related: flash detection code tweak.</p></li>
              <li><p>isNaN() check for HTML5 loading (saw one under Safari, in testing).</p></li>
              <li><p>Use new Audio(null) vs (), Opera 9.64 expects URL argument; throws WRONG_ARGUMENTS_ERR otherwise. Doesn't implement canPlayType() either, but both are fixed in future releases.</p></li>
			 </ul>

			 <p><b>As of the V2.97.20110123 release of SM2:</b></p>
			
			 <ul>
			  <li><p>New (experimental) <code>soundManager.useGlobalHTML5Audio</code> attribute, enabled by default for mobile + iOS. Enables use of a single audio object, re-used for loading and playing all sounds. iOS currently can only play one sound at a time, so this limitation is safe for now. The global object fixes previous regression of play-through/playNext()-style behaviours.</p></li>
			  <li><p>Sound recycling with new global audio feature should work better than in prior (development) versions.</p></li>
			  <li><p>Improved broken Safari/Snow Leopard HTML5 audio situation: HTML5 mode is no longer disabled - and if available, Flash is used to play MP3/MP4 content to work around known playback issues with native HTML5 audio.</p></li>
			  <li><p>New (experimental) <code>soundManager.requireFlash</code> property (default: false.) If true, prevents HTML5-only mode on devices with both HTML5 and Flash. May be useful when HTML5 is enabled (and can play MP3), but Flash is desired to play RTMP content etc. As of this version, will only use Flash for RTMP.</p></li>
			  <li><p>Fix for <code>type:'audio/mp3'</code> returning false on <code>canPlay()</code>. Timer update-while-paused tweak.</p></li>
			  <li><p>More event listeners, ignore events on destroyed sounds, improved event clean-up, "seek before load" fix</p></li>
			 </ul>

 			 <p><b>As of the January 1, 2011 (V2.97a.20110101) and December, 2010 releases of SM2 (V2.97a.20101221):</b></p>
                         <ul>
                          <li><p>The <code>bytesLoaded</code> and <code>bytesTotal</code> properties may become less-relevant under HTML5 due to non-linear HTTP downloading (using ranges and partials), but they are still provided under Firefox at this time.</p></li>
                          <li><p>Related to bytes loading/total, a sound's <code>onload</code> event may not always be fired (Mozilla currently discourage use of the DOM <code>loaded</code> event), again because of range requests and the ability to arbitrarily seek within a file.</p></li>
                          <li><p>Basic support for the W3 <code>TimeRanges</code> implementation of sound buffering (ie., loaded data) has been implemented. This gives an idea of "total time loaded", but again, is not necessarily sequential.</p></li>
                          <li><p>HTML5 audio is disabled for all versions of Safari (4 and 5) on Snow Leopard (OS X 10.6.3 - 10.6.5) until Apple fixes issues with audio loading and playback due to bugs in "underlying frameworks." See <a href="https://bugs.webkit.org/show_bug.cgi?id=32159#c9" title="Safari Snow Leopard HTML5 Audio Bug">Webkit #32159</a>. HTML5 audio in Safari on Windows (provided QuickTime is installed) does not have the same fatal bug.</p></li>

			 <p><b>As of the August, 2010 release of SM2 (V2.96a.20100822):</b></p>
			 <ul>
			  <li><p>Safari 5.0.1 (533.17.18) on Snow Leopard (10.6.x) continues to show buggy HTML5 audio load/playback behaviour. Apple are aware of the regression, which began with Safari 4.0 on Snow Leopard (perhaps with the new QuickTime.) See <a href="https://bugs.webkit.org/show_bug.cgi?id=32159#c9" title="Safari Snow Leopard HTML5 Audio Bug">Webkit #32159</a>.</p></li>
			  <li><p>iPad/iPhone iOS4 will now play a sequence of sounds if using <code>onfinish()</code> to create/start the next (eg., the Muxtape-style playlist on the SM2 homepage will play through once the user starts it.) In any event, user interaction is always required to start the first sound.</p></li>

			 <ul>
			  <li><p>Safari 5.0 (533.16) on OS X Snow Leopard (10.6.x) continues to show buggy HTML5 audio load/playback behaviour, same as with Safari 4.0.5 on Snow Leopard only - may be related to underlying QuickTime implementation (a guess, at this point.) SM2 will disable HTML5 audio support by default for this specific browser + OS combo. See <a href="https://bugs.webkit.org/show_bug.cgi?id=32159#c9" title="Safari Snow Leopard HTML5 Audio Bug">Webkit #32159</a> for discussion + testcases.</p></li>

			 <p><b>As of the May, 2010 release of SM2 (V2.96a.20100520):</b></p>
			 <ul>
			  <li><p>Safari 4.0.5 on OS X Snow Leopard (10.6.x) appears to have an annoying bug where audio inconsistently fails to load / play; SM2 will currently disable or ignore the HTML5 feature on this exact browser + OS version. See <a href="https://bugs.webkit.org/show_bug.cgi?id=32159#c9" title="Safari Snow Leopard HTML5 Audio Bug">Webkit #32159</a> for discussion + testcases. Note that Safari on OS X 10.5 "Leopard" and on Windows <i>do not</i> appear to have this bug; it seems to be limited to Snow Leopard, seen on OS X 10.6.3.</p></li>
			  <li><p>Some browsers (and iPad 3.2?) do not fire <code>progress</code> events, and/or do not implement bytesLoaded/bytesTotal-style attributes.</p></li>
			  <li><p>iPad 3.2 appears to be able to only play one sound at a time, and will terminate other sounds.</p></li>
			  <li><p>iPad 3.2 may also loop AAC+ (HE-AAC) and WAV sounds, perhaps not firing onfinish() and resetting the position to 0 each time, but is fine with MP3s. This has been observed, but not fully-tested.</p></li>
			  <li><p>Looping in HTML5 is either "infinite" or "none". A wrapper may be created for SM2 so that a number of loops can be specified, as with Flash. This is not yet implemented.</p></li>
			  <li><p>Panning (left/right channel balance) does not appear to be in HTML5.</p></li>
			  <li><p>Flash-only features such as ID3 tag reading, waveform and spectrum data will simply be ignored, and their related events will not fire on SMSound objects which are using HTML5.</p></li>
